How to work it out

  1. Difference: 35 − 51 = -16
  2. Divide by the starting value: -16 ÷ 51 = -0.313725
  3. Multiply by 100: -31.3725%
  4. Check: Work forwards from the start: 51 × (1 − 0.313725) = 51 × 0.686275 = 35.

In a spreadsheet: =(35-51)/51*100. Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.

What the result means

The new value is 68.6275% of the old one: for every 100 at the start there are now 68.6275, so 31.3725 out of every 100 have gone.

Sales: a price cut from $51 to $35 is a 31.3725% discount.

Why the change back is different

A 31.3725% fall followed by a 31.3725% rise does not bring you back to 51: it gives 45.9804. The second percentage is taken of 35, not of 51, so to undo this change you need 45.7143% instead.
